SumWise for Windows
See how your formula behaves.
Plot a supported function in SumWise Desktop, inspect approximate coordinates and keep the graph with your calculations. Start with the parabola below; explore 3D surfaces through the separate guide.
Looking for surfaces? Follow the 3D graphing guide. The ordinary graph examples below remain 2D commands.
Explore a parabola before sharing the plot
Plot y = x² − 4x + 3 over a range that includes both crossings and the minimum.
Copy this expression into SumWise, then press Enter to calculate.
graph x^2 - 4*x + 3 from -2 to 6Expected result: The parabola crosses the x-axis at x = 1 and x = 3, with its minimum at (2, −1).
These positions follow from the polynomial; inspected graph coordinates and pins are approximate. A picture is not a saved editable workspace. Continue with the documented workflow.

Unit-aware comparisons
Use Guided formulas to compare two to four supported scenarios on shared unit axes. For Current, vary Resistance from 1 to 4 ohm and fix 12 V / 24 V. Review assumptions, Prepare, Insert and explicitly calculate. Generate Values when needed; tables include hidden curves and per-curve domain gaps. At 3 ohm these scenarios sample 4 A / 8 A.
Samples and pins are Approx, not exact roots. Supported graph state can be saved in supported workspaces; Values must be generated again after reopening. Read the scope introduced in 2.6. Check Store for the version available to your account.
Move from a typed function to an interactive graph without leaving your scientific calculation workspace. SumWise plots multiple real-valued functions, lets you inspect and pin coordinates, supports focused visual calculus workflows, and exports a clean graph as PNG.

Plot Multiple Functions in One View
A graph command can include more than one expression and an explicit x-range. This makes it practical to compare functions instead of opening separate graph windows. For a simple comparison, enter:
graph sin(x), cos(x) from -10 to 10Each plotted function appears in the graph legend with its own color and visibility control. You can hide or show a curve from the graph interface while keeping the other functions in view. Zoom, pan, and reset controls help you move from a broad view to a useful local one.
Inspect and Pin Coordinates
Move near a visible curve to inspect its function label and an approximate coordinate. Click an inspected point to keep the coordinate pinned while you continue exploring the graph. A pinned coordinate can also be copied as reusable text.
An explicit range helps put the important part of a graph on screen. The following quadratic has two real roots and a visible minimum in the selected range:
graph x^2 - 4*x + 3 from -2 to 6For a guided introduction to quadratic graphs, follow How to Graph a Parabola on Windows. For a broader comparison workflow, use the multiple-function graph tutorial.
Verified Graph Commands to Try
These current SumWise commands cover general plotting and focused visual calculus workflows:
Enter one command per calculation.
graph sin(x), cos(x) from -10 to 10graph x^2 - 4*x + 3 from -2 to 6graph_tangent(x^2, 3) from -2 to 6graph_area(sin(x), 0, pi) from -1 to 4graph_roots(x^2 - 1) from -3 to 3The commands are intentionally explicit: they state the expression, any supported overlay inputs, and the useful range. More copy-ready commands are available on the SumWise Examples page.
Connect a Calculation to Visual Calculus
Supported graph helpers can add a tangent line, shade a definite integral region, or mark roots and extrema. The tangent workflow connects the curve, tangent point, slope, and exact tangent-line expression in the same result.
graph_tangent(x^2, 3) from -2 to 6 shows the point (3, 9), slope 6, and tangent line 6*x - 9.Continue with the critical-points tutorial or the Derivative and Integral Calculator for Windows guide to connect graphing with supported symbolic results.
Copy or Export the Graph
SumWise can copy the current graph as an image or save a clean, high-resolution PNG of the visible graph. The export includes the current viewport, visible curves, supported overlays, and a pinned point when present. Transient hover state and the surrounding application controls are excluded from the saved graph image.
A Local Windows Graphing Workflow
Graph calculation and interaction are designed to run locally after SumWise is installed, without depending on a browser or cloud calculation service. Microsoft Store still handles installation, trial, purchase, and license verification.
Honest Graphing Scope
SumWise graphing focuses on multiple real-valued functions, paired data plots, linear regression, and supported visual calculus overlays. The separate 3D surface tool adds bounded 3D plotting. SumWise is not an exam-certified handheld calculator. Symbolic and calculus helpers cover supported workflows rather than universal mathematical cases.
Graphing Calculator FAQ
Can SumWise graph more than one function?
Yes. A graph command can include multiple functions, and visible curves can be controlled from the graph legend.
Can I inspect a curve?
Yes. SumWise supports curve inspection, pinned coordinates, and coordinate copying for visible plotted curves.
Can I export a graph?
Yes. You can copy the graph as an image or save a clean PNG of the current graph view.
Does SumWise graph in 3D?
Yes. In 3.1, open the separate Plot 3D surface tool for a bounded explicit x/y surface. This page covers the existing 2D, paired-data and regression workflows.

The full-featured seven-day trial is available through Microsoft Store only. SumWise Desktop costs US$24.99 one-time, with no SumWise Desktop subscription. The separate Direct purchase section explains the initial unsigned download and manual delivery conditions before payment.
Established 2D workspace limits (introduced in 2.6): calculations and supported graphs reopen as snapshots, not live dependencies. Generate Values again after opening; a PNG or selected HTML report is presentation output, not editable work. Confirm the supplied version before Direct payment.
